# `set`

Inside code blocks you can also assign values to variables. Assignments use the `set` tag and can have multiple targets.

Here is how you can assign the `bar` value to the `foo` variable:

    {% set foo = 'bar' %}

After the `set` call, the `foo` variable is available in the template like any other ones:

    {# displays bar #}
    {{ foo }}

The assigned value can be any valid Twig expression:

    {% set foo = [1, 2] %}
    {% set foo = {'foo': 'bar'} %}
    {% set foo = 'foo' ~ 'bar' %}

Several variables can be assigned in one block:

    {% set foo, bar = 'foo', 'bar' %}

    {# is equivalent to #}

    {% set foo = 'foo' %}
    {% set bar = 'bar' %}

The `set` tag can also be used to ‘capture’ chunks of text:

    {% set foo %}
        <div id="pagination">
            ...
        </div>
    {% endset %}

Caution

If you enable automatic output escaping, Twig will only consider the content to be safe when capturing chunks of text.

Note

Note that loops are scoped in Twig; therefore a variable declared inside a `for` loop is not accessible outside the loop itself:

    {% for item in list %}
        {% set foo = item %}
    {% endfor %}

    {# foo is NOT available #}

If you want to access the variable, just declare it before the loop:

    {% set foo = "" %}
    {% for item in list %}
        {% set foo = item %}
    {% endfor %}

    {# foo is available #}
